89 for supplying construction power at 132kV level to 2x800 MW Thermal power plant at Godda by M/s Adani power--JUSNL

JUSNL vide letter dated 18-08-2017 informed that M/s Adani Power Jharkhand Ltd. (APJL) is setting up 2x800 MW thermal power plant at Godda. Availing power supply for construction M/s


Adani Power has requested for construction of LILO of 132kV Dumka-Lalmatia D/c line at loc. 89 on cost deposit basis. Details are enclosed at Annexure-B8. 132kV Lalmatia-Dumka D/C line is covered under Farakka islanding scheme. Members may discuss. Deliberation in the meeting It was informed that the PLCC of 132kV Lalmatia-Dumka D/C line is being used under Farakka islanding scheme, so the LILO of both ckts might reduce the reliability of PLCC system and hamper the operation of Farakka islanding scheme. In view of above, OCC decided that LILO of one ckt of 132kV Dumka-Lalmatia D/c line may be done for meeting the requirement of construction power of 2x800 MW power plant of M/s Adani Power. Item No. B.9: Flexible jumpering arrangement for bypassing substations, prone to

inundation during monsoon, for ensuring continuity of important corridors and power evacuation from power stations--ERLDC

During the current monsoon season, quite a few substations in Eastern Region viz. Alipurduar(PG), Kishanganj(PG), Dalkhola(PG) and Motihari(DMTCL) had to be completely shutdown, due to massive waterlogging. Outage of Kishanganj S/Stn posed constraint in power evacuation of Sikkim generators and surplus power of NER while outage of Alipurduar S/stn weakened the inter-regional connectivity between ER and NER. Such substations typically have 2 nos incoming and 2 nos outgoing lines and lie either along a major intra/inter-regional corridor or along the evacuation route of a major power station. Under the above mentioned situation, it is desirable that continuity of the transmission corridor be maintained by directly connecting the incoming and outgoing lines, bypassing the inundated substation. However, such network re-configuration is possible only if facility for jumpering conductors at appropriate locations is already in place. This practice is already being followed at a number of locations in Western Region. Members may please identify the substations where the above proposed arrangement can be utilised for maintaining grid security under flood situations. Members may discuss. Deliberation in the meeting ERLDC explained that the flexible jumpering arrangement may be done for 400 kV Binaguri-Kisheenganj-N.Purnea D/C and 400kV Binaguri-Alipurduar-Bongaigaon D/C lines for bypassing the LILO points i.e. 400kV Kishanganj(PG) and Alipurduar(PG) S/s so that the same lines may be directly connected during the emergencies like flood situations at LILO points. The possibility may be explored as these elements are very important in terms of hydro power evacuation and long outages of these elements may endanger the grid security. The details are enclosed at Annexure-B9. The other such elements (LILOed at Dalkhola, Motihari (DMTCL) etc) may also be explored which are under threat during flood and other emergencies. OCC felt that such kind of bypassing arrangement will help the grid to improve the reliability during emergencies when substation is not available in service. OCC advised Powergrid to explore the possibilities of implementing such bypassing arrangement for above elements and for other important elements, if any. Powergrid agreed to do the survey and explore the possibilities.


Item No. B.10: Concerned members may update the latest status.

B.10.1. Status of construction of 400 kV Sterlite-Jharsuguda D/C sections In 134th OCC, OPTCL updated the status as follows:

Activities Nos Status as updated in 35th TCC

Status as updated in 134th OCC Remarks

Stringing /OPGW Cabling & Testing

20.5 Km 9 km completed 16 km completed

Sub station Bay 2 Bay construction completed Testing going on

OPTCL informed that the construction of the dedicated line would be completed by 15th July, 2017 in all respects. Further, GRIDCO/OPTCL added that 7 No. of towers of 400KV Vedanta-Meramundali D/C line have been severely damaged due to whirlwind and cyclonic storm on 15-06-2017 night between Location No.7-0 to 8-0. As a result, GRIDCO could not avail State share of power through the said line and is solely dependent on LILO connectivity to avail IPP power from M/s. Vedanta Limited. In view of the above, GRIDCO/OPTCL requested that the disconnection of interim LILO connectivity scheduled on 01-07-2017 for M/s. Vedanta Ltd may please be deferred until the restoration work of Vedanta-Meramundali line and commencement of power supply to the State through this line.

After detailed deliberation, OCC agreed to extend the LILO connectivity till 15th July, 2017. It was also decided that the removal of LILO could be reviewed subject to the completion of dedicated line as per the latest schedule i.e. by 15th July, 2017. Accordingly, a special meeting to review the removal of LILO connectivity was held at ERPC on 14th July 2017 and the minutes are available at ERPC website. In 135th OCC, OPTCL updated the status as follows:

Activities Nos Status as updated in 35th TCC

Status as updated in 135th OCC Remarks

Tower Foundation 64 64 64 Completed Tower Erection 64 59 64 Completed

Stringing /OPGW Cabling & Testing

20.5 Km 9 km completed 17.8 km completed

Sub station Bay 2 Bay construction completed Testing going on

After detailed discussion, it was decided that Vedanta should complete the line construction and bay works by 30th July, 2017. It was also decided that the LILO of Vedanta Ltd may be disconnected from 16th August, 2017. OCC advised OPTCL to complete the line by 1st week of August 2017. Members may discuss.


Deliberation in the meeting OPTCL informed that construction of dedicated 400 kV Vedanta- Jharsuguda line has been completed except 800m stringing which involves crossing of two 400 kV lines. The stringing work is being done manually because of severe rains. However, OPTCL assured that the line would be commissioned by September, 2017 in all respects.

OPTCL requested to extend the deadline for removal of LILO till the restoration of 400 kV Vedanta-Meramundali D/C line which is expected by 2nd week of September, 2017.

OCC advised OPTCL not to link the restoration of 400 kV Vedanta-Meramundali D/C line and stressed for early commissioning of 400 kV Vedanta-Jharsuguda line at least by ensuing TCC/ERPC meetings. With above view OCC referred the issue to TCC for further guidance. Special Protection Scheme(SPS) of Sterlite (VAL) –ERLDC Sterlite has installed capacity of 4X600MW (2400MW) with smelter load of More than 1000MW grid-connected plant. In case of loss of smelter load or evacuation path units might trip due to mismatch of load and generation. Sterlite had already implemented SPS to minimize the impact of such major load generation mismatch on the grid. In an earlier OCC meeting VAL agreed to share their presently implemented SPS details. But thereafter, VAL did not submit anything to ERLDC/ERPC. In 135th OCC, OPTCL was advised to submit the present SPS settings to ERPC and ERLDC within a week. SLDC OPTCL and Vedanta may update. Deliberation in the meeting OPTCL was advised to submit the present SPS settings to ERPC and ERLDC within a week.

B.10.2. Enabling of 3-Phase Auto Reclose at 132 kV North Bengal and Sikkim areas to minimize element outages due to transient faults -- Powergrid

During rainy season In North Bengal and Sikkim area, high element outages observed of 132 KV level. Mainly from past experience it is observed that 90% of the fault is of Single Phase to Ground fault and transient in nature. However as per general practice 132 KV level CB’s are of mechanically ganged and any single phase fault also causing tripping of all three phases. To make system more dynamic it is prudent to go for, three phase auto reclosure for any single phase Fault in the 132 KV lines. Only by introduction of A/R facility line availability may be increased in the tune of 90% i.r.o present situations. POWERGRID proposed to implement the same however other constituents as well as ERLDC may give respective views. Upon concurrence detailed road map for Implementation will be given. In 132nd OCC, Powergrid informed that in North Bengal and Sikkim area most of the time the 132 kV lines were tripping on transient fault and the system can be saved by implementing 3-phase auto-reclosure scheme. OCC discussed the matter in detail and agreed in principle for implementation of 3-pase auto-reclosure scheme for 132 kV lines. Further, it was decided that the implementation would start with North Bengal and Sikkim area. Further, OCC advised Powergrid to submit a report on the status of PLCC/telemetry, A/R facility etc. for both ends of each 132 kV lines of North Bengal and Sikkim area.


In 134th OCC, Powergrid informed that the 3-phase auto-reclosure scheme for 132kV Rangpo-Gantok line will be implemented by July 2017. In 135th OCC, Powergrid informed that Rangpo end relay will be installed within a week and replacing the relay at Gangtok end will take time. OCC advised Powergrid to submit a report on the status of PLCC/telemetry, A/R facility etc. for both ends of each 132 kV lines of North Bengal and Sikkim area. Powergrid may update. Deliberation in the meeting OCC advised Powergrid to submit a report on the status of PLCC/telemetry, A/R facility etc. for both ends of each 132 kV lines of North Bengal and Sikkim area.

B.10.3. Status of Installation of STATCOM in Eastern Region In the 15th meeting of SCM it was agreed to install STATCOM in combination with mechanically switched Reactors (MSR) and Capacitors (MSC) and co-ordinated control mechanism of MSCs and MSRs at Ranchi, Rourkela, Jeypore and Kishanganj substations in Eastern Region as given below

The matter was again discussed in the 28th ERPC/TCC meeting held on 12th -13th September, 2014 at Goa, wherein, it was decided that POWERGRID may go ahead with implementation of the STATCOM project in Eastern Region with debt – equity ratio of 70:30 funding. The debt part should be refunded through PSDF and Equity Component (30%) to be funded by POWERGRID to be recovered through regulated tariff mechanism. CTU should initiate the process of availing fund from PSDF. POWERGRID may kindly inform tentative dates for commissioning of STATCOMs at the above mentioned locations.

Deliberation in the meeting Members noted. Item No. B.16: Data of Peak Demand – Submission of hourly power cut data The peak demand met figure calculated by CEA is a part of the monthly Power Supply Postion Report prepared by CEA, based on the data provided by five Regional Power committee (RPCs), who in turn collect the data from State / UTs and RLDCs. As per the present methodology being adopted for calculation of States /Regional peak demand met, the figure of peak demand met at any time in the month is taken as peak demand met for the month. For all India monthly peak demand met, the sum of five regional peaks met, which may occur at different points of time is taken. The above methodology has been reviewed and it has been decided with the approval of Chairperson, CEA that Peak demand Met and Peak Demand in the country should be based on hourly all India demand data. The matter was taken up with POSOCO for getting the hourly data of peak demand met for each month in respect of all the regions in the country in the first week of following month and they have assured to furnish the same. To calculate the demand, data of hourly scheduled and unscheduled power-cuts / load shedding is also required, which is not available with POSOCO. It is, therefore, requested that hourly figures of scheduled/ unscheduled power cuts/load shedding data may be collected from States / UTs and the same may be sent to CEA every month as per above schedule in the enclosed format, in spread sheet, so that hourly figures of peak demand can be calculated and incorporated in Power Supply Position report. This data for a month may kindly be sent in the first week of each month, along with PSP data, starting from the data for the month of February, 2015.

In case of fibre cut between Kasba to ERLDC, all the 8 nos PMUs data stopped reporting to ERLDC (happened on 16/May/2017 from 04:25 Hrs to 12:49 Hrs). There is no redundant path provided for these communication links. So, it is requested POWERGRID to shift these PMUs’ communication path / equipment so that the protection path of ULDC network would be used and this type of outage could be avoided. Communication link for Patna PMU is taken from PowerTel. It is also requested to POWERGRID that communication path may also be shifted for Patna PMU so that PowerTel communication could be removed. In 134th OCC, ERLDC informed that work is not yet completed. Powergrid informed that 8 PMUs communication system have been shifted to ULDC network. OCC advised ERLDC to send the details of requirement to Powergrid. Accordingly, ERLDC has sent the detailed requirement for shifting of communication link to POWERGRID ULDC on 14-07-2017. The same is attached at Annexure – B.21. In 135th OCC, Powergrid agreed to complete the work within a month. PGCIL may update. Deliberation in the meeting ERLDC has placed the updated status. The status is enclosed at Annexure-B21. Powergrid agreed to complete the work at the earliest.

In 120th OCC, ERLDC informed that every month they were updating the status and posting at ERLDC website. 134th OCC advised all the respective constituents to ensure the availability of telemetry data to ERLDC. Members may update. Deliberation in the meeting


ERLDC presented the status of telemetry data availability. The latest status is enclosed at Annexure-B22. OCC advised all the respective constituents to ensure the availability of telemetry data to ERLDC.

a) Frequent failure of JITPL data to ERLDC: Real time SCADA data from JITPL is frequently failing (May-17: 24% & June-17 (up to 18th): 62%). It was observed that

Microwave terminal equipment at Talcher HVDC end is getting hanged quite frequently causing failure of real time data to ERLDC.

The direct line from JITPL to Angul 765/400 kV pooling station is available but real time SCADA data is yet to be diverted through this path.

The voice connectivity from JITPL to ERLDC is yet to be provided / integrated with Hot Line Voice Communication installed by M/s Orange.

The same was informed to JITPL several times verbally and through a letter vide ref no: ERLDC/SL/2017-18/621 dated: 3rd May 2017 but it is yet to be diverted / provided. In 134th OCC, JITPL representative was not available in the meeting. ERLDC informed that SCADA data from JITPL is frequently failing and JITPL is not responding even with repeated persuasions. OCC advised ERLDC to take suitable action against JITPL and stop entertainment of STOA application till SCADA data is restored. ERLDC informed that they will be constrained to stop all STOA transactions with effective from 00:00 Hrs of 01st August, 2017, upon unavailability of SCDA data at ERLDC. In 135th OCC, it was informed that the data is coming through Powergrid substations via PLCC link. Because of some commercial issues between JITPL and Powergrid the direct link is yet to be restored. OCC advised JITPL and Powergrid to settle the commercial issues bilaterally and restore the JITPL data availability to ERLDC. JITPL may update about the action plan for restoration of real time SCADA data, route diversion of data flow through POWERGRID Angul pooling station & voice connectivity integration with Orange exchange. JITPL and ERLDC may update. Deliberation in the meeting JITPL informed that presently they are communicating ERLDC with a radio link, which is an interim arrangement and is not reliable and they are trying hard to maintain it. However, they had planned to make PLCC system operational for uninterruptable communication to ERLDC. But Powergrid is not allowing them to shift NSK modem of PLCC system from Bolangir(PG) S/s which is the property of JITPL. JITPL added that they were in process of settling the commercial issues with Powergrid and requested Powergrid to cooperate. OCC took serious note of the issue and felt Powergrid should not interrupt in establishing the proper communication system for SCADA/telemetry data to ERLDC. OCC felt that Powergrid


should not take up commercial issue by staking the grid security and advised Powergrid to take up the commercial issue separately.

b) Delay in restoration of 400kV JITPL-Angul line II on 04-08-2017 JITPL vide letter dated 09.08.2017 informed that they have received the charging code from ERLDC at 23:39 hrs on 04.08.2017. But the line could not be charged due to no communication from Angul S/s. After repeated pursuation the line was charged at 11:19 hrs on 05.08.2017. JITPL and Powergrid-Odisha may explain. Deliberation in the meeting JITPL informed that this is the third time Powergrid has delayed to charge the JITPL line because of pending commercial issues. ERLDC informed that till date no information was made available by Powergrid on delayed charging of the line. In OCC meeting also Powergrid failed to give satisfactory explanation on delayed charging of the line. OCC took serious note of delayed charging of the line and endangering the grid security by forcing a 2x600 MW power plant of JITPL connectivity through a single line. After detailed deliberation, OCC felt that at the stake of grid security, Powergrid should not take up the commercial issues. Further, OCC advised Powergrid to submit the reason for delayed charging at the earliest and decided to refer the issue to TCC. Item No. B.23: Less Generation/ Pumping at PPSP, WBSEDCL --ERLDC Since last few days, two units of PPSP were not running either in PUMP mode or Generation mode due to leakage in pipe lines between upper and lower dams. Due to outage of units of PPSP and lower side generation in other state generator, West Bengal is over drawing around 200 to 300 MW during peak hour. WBSEDCL, may please inform the status of the PPSP generation revival plan and their planning of load management during PUJA days if PPSP problem would not solved. Deliberation in the meeting WBSEDCL informed that the issue has been resolved and PPSP generators are in service. Item No. B.24: Despatch of power from Farakka-III under RRAS--ERLDC The matter of participation of Farakka – III under RRAS was deliberated and discussed in 35th Commercial Committee Meeting of ERPC, Where in NTPC, Farakka – III sought some time to sort out the commercial implications with their corporate office. NTPC, Farakka – III may please update the status. Deliberation in the meeting NTPC informed that Farakka Stage-III is ready to participate in RRAS.


OCC advised FSTPS Stage-III to furnish the necessary formats (AS-1, AS-2 & AS-3) at the earliest to commence the participation in RRAS.

In this regard, it is to bring to the kind notice of the members that, NLDC is coordinating for trans-national exchange of power with Bhutan, Nepal and Bangladesh for 132 kV and above lines. However, in case of 132 kV lines between India and Nepal which are owned by erstwhile Bihar State Electricity Board (BSEB) are being operated without involving NLDC and ERLDC. These lines include 132 kV Balmiknagar (BSEB)-Surajpura S/C and 132 kV Kataiya (BSEB)-Duhabi S/C. 132 kV Raxaul – Parwanipur D/C is also expected to be commissioned shortly. In this regard, it is pertinent to mention here that 132 kV Rangia (Assam) – Motanga (Bhutan) line owned by AEGCL is also being operated by NLDC in coordination with Bhutan, Assam SLDC and NERLDC. Therefore, all the states of Eastern Region are requested to take following actions with reference to the 132 kV & above lines with neighbouring countries:

1) Provide first time charging documents and take consent from ERLDC/NLDC before first time charging in accordance with NLDC procedure for interconnection of new transmission element.

2) Provide real time data of the lines and all other elements impacting power transfer on these lines.

3) Take real time code from NLDC/ERLDC for switching. 4) Inform NLDC/ERLDC regarding the quantum and limit of power flow. 5) Inform OCC and take approval from OCC for all planned outages. 6) Inform and take consent/approval from NLDC/ERLDC regarding the planned and

emergency outages in accordance with NLDC Outage Planning procedure. 7) Inform NLDC/ERLDC regarding the details of tripping (including lines below 132 kV as

well). 8) Inform NLDC/ERLDC regarding the power transfer on all lines (including lines below 132

kV as well) with neighboring countries on daily basis. Members may discuss. Deliberation in the meeting OCC advised all the respective constituents to comply the above and share the above listed information to ERLDC and NLDC on regular basis.

Members may update. Deliberation in the meeting Members noted. Black start and FGMO/RGMO operation of Purulia Pump Storage Project (PPSP) units of WBSEDCL – ERLDC In the 130th OCC Meeting held on 17th February, 2017 WBSEDCL informed that they had contacted OEM Toshiba for feasibility of black start and OEM required to conduct a simulation with CEA recommendations. OCC advised WBSEDCL to expedite the process as the time extension granted by CERC for making black-start and FGMO/RGMO operational in PPSP units, was going to lapse by March.2017. In 135th OCC, WBSEDCL informed that they have not received any comments from OEM.


ERLDC informed that making black-start functional at PPSP has therefore become uncertain as it is completely dependent on the OEM, who is not responding to the requirement of WBSEDCL. It may be noted that WBSEDCL had already sought 6 month time from CERC and no progress could be made even after expiry of 11 months. Since such delay and uncertainty in execution of the work is ultimately affecting the security of Eastern Regional grid, matter may escalated to MOP / CEA for hiring the professional service of competent vendors / consultants so that black-start capability at PPSP could be operationalised within a definite target date. WBSEDCL may update. Deliberation in the meeting WBSEDCL informed that they are putting all the efforts to implement the black start facility for PPSP. Testing of DG sets meant for Black start

Item no. C.2: OPERATION OF HYDRO POWER PROJECTS IN PEAKING MODE

CEA vide letter dated 18.07.17 informed that POSOCO has carried out operational analysis of various hydro stations in the country and observed that despite 40.6 GW of peaking hydro capacity only about 33 GW peak generation is carried out on all India basis. According to POSOCO, this is on account of a number of hydro stations, particularly in state sector, which are not being operated in peaking mode. In order to examine the above observation, a Sub-committee has been constituted by the MoP under Chiarperson, CEA with heads of POSOCO, NHPC, SJVN & THDC as members and Director (H), MoP as the Member Convenor. The Sub-Committee has held three meetings with the concerned hydro generating stations and concluded that there is scope for about 2000 MW additional power generation from hydro stations during peak hours. It has been desired by the Chairperson that the matter of utilization of hydro stations in peaking mode be made a regular agenda item for discussion at the monthly OCC meetings while discussing operational planning for the month ahead and analyzing the operation in the previous month. In 135th OCC, ERLDC presented the performance in peaking mode for hydro generations in Eastern Region. OCC decided to review the performance of hydro generators in peaking mode in monthly OCC meetings As informed by ERLDC, during review it was observed numbers of hydro units of state sectors were under outage due to various reasons and also some units were running at de-rated capacity compare to their installed capacity. In this regards, it is requested to all State (through SLDC), ISGS and IPP owned hydro generators to update the status of the hydro units on bar, hydro units under outage along with reason to ERLDC and ERPC on daily basis in the following format.

Item no. D.4: Reporting of voltage deviation indices (VDl) for select S/Stns in ER ERLDC submitted the Voltage Deviation Index (VDI) of selected 400 kV Sub-stations for July, 2017 of Eastern Region which is enclosed at Annexure- D.4. Members may note. Deliberation in the meeting Members noted. Item no. D.5: Additional agenda

1. Sustain Under-injection by ISGS generators during RRAS—ERLDC During July and August 2017, NLDC triggered RRAS UP for ISGSs generators of Easter Region on several occasions. However it is observed that some of the ISGS failed to maintain their generation as per schedule and continuous under-injection was observed during the above mentioned period. As per section 5.4 of Detailed Operating procedure of RRAS, “The continuity of the RRAS shall be ensured by the RRAS provider over the period of the despatch”. However, this was continuously violated by ISGS stations of ER. As per clause 9.13 of Detailed Operating procedure of RRAS Quote - Sustained failure, i.e. failure to provide the RRAS (barring unit tripping) by RRAS Provider(s) more than three (3) times during a month shall be brought to the notice of the CERC

- Unquote

Detailed performance of ER ISGS from RRAS point of view would be presented during the meeting. ISGSs are therefore requested to exercise due care while declaring their respective DCs, so that actual generation as per the total schedule issued, can be maintained by them.

Deliberation in the meeting ERLDC presented the performance of the RRAS provider generators during July & August 2017 and informed that in real time Barh, FSTPP stage I & II and KhSTPP stage I & II generators were failed to maintain their generation as per schedule. Presentation is enclosed at Annexure-D5.1. OCC advised NTPC to follow the RRAS schedule strictly. OCC advised ERLDC to monitor the status for one week and even if there is no improvement, the acion may be initiated as per the provisions of IEGC. Further, OCC advised ERLDC to place the status in next OCC meeting.

2. Delineation of O&M responsibilities of various assets of the ISTS--ERLDC With opening up of transmission sector for private participation and rapid addition of new ISTS elements through TBCB route, multiple transmission licensees are now involved, in so far as ownership and maintenance of the regional ISTS is concerned. A single transmission line may be partly owned by one licensee and partly by the other, while the bay equipment, panels etc. at each of the ends may be owned / maintained by two different transmission licensees. In the above backdrop, as the apex body to ensure integrated operation of the regional power system, it becomes essential for RLDCs to be accurately aware of the scope


of responsibilities of each of the licensees, in order to discharge its responsibilities in a smooth and efficient manner. A list of transmission elements in Eastern Region together with their ownerships as per information available with ERLDC is enclosed at Annexure-D5.2. It is requested to kindly go through the list and indicate the agencies responsible for maintenance of line, ensuring real time data, furnishing relay indication, DR etc. in respect of each of the elements and inform ERLDC wherever necessary updating / correction is required to be incorporated.

Deliberation in the meeting

OCC advised all the constituents to update the status as given in the annexure and send it to ERPC and ERLDC within a week. 3. Trail operational certificate for underground fiber optic link from Jakkanpur to SLDC, Patna-

BSPTCL End to end testing of UGFO link between Jakkanpur to SLDC, Patna has been carried out on 03-10-16. Route survey with M/S KEC was carried out on 31-05-17. It was observed that no marking to identify route, location of splice chamber and pits. No provision of clause of standard technical specification of UGFO of PGCIL was followed either regarding the route markers, constrcution of manholes, warning bricks etc. BSPTCL repeatedly requested PGCIL authorities to furnish the technical specification and the SAT procedure of UGFO, but the same has not been provided yet. This may affect the maintenance of UGFO link further. Details are enclosed at Annexure-D5.3.


It was agreed that Powergrid and BSPTCL will do the joint inspection. Powergrid agreed to provide the technical specification and SAT procedure of UGFO to BSPTCL. 4. Ethernet link for integration of Kishanganj SAS GSS with SLDC, Patna - BSPTCL Synchronous Digital Hierarchy (SDH) has been installed in Kishanganj (PG)and approach cable laid out up to connecting SDH for integration of SDH of Kishanganj (New) GSS. Ethernet link for integration of SDH of Kishanganj SAS GSS with SLDC, Patna for monitoring of real time data and voice of 220/132/33 kV Kishanganj (New) GSS as well as connecting GSS for ULDC purpose is required on priority basis. Details are enclosed at Annexure-D5.4.


Powergrid agreed to resolve the issue.

Annexure-B36A

CERC order

• Petition No. 84/MP/2015, Date of order: July 31, 2017 section 23 (a):

– “… the Commission, starting from the month of September, 2017 shall be closely watching the primary response of ISGSs as reported by POSOCO/NLDCs.

– At the State level, SLDCs shall report the frequency response of intra-State generators to the concerned SERCs.”

Section 23(b)

• “… SLDCs through the assistance of POSOCO shall start the process of selecting independent third parties capable of undertaking periodic checkups to monitor the RGMO/FGMO response.

• To start with selected independent third parties shall be sent to the generating stations which are not providing the desired RGMO/FGMO response….”

Section 23(b) contd.

• “…Independent Third Parties shall ensurethat the generator has not, in any way,prevented/disabled the governor fromproviding the desired response.

• In case, even after enabling the governors,units are not able to provide the desiredresponse as per the provisions of the GridCode, third parties, based on thesubmissions of the generators, shall bringout the technical constraints, if any, whichlimit the primary response of the units.”

Section 23(c)

• “All ISGSs are directed to provide primaryresponse compulsorily in terms ofRegulation 5.2 (f), (g), (h) and (i) of theGrid Code failing which we would nothesitate in initiating action under Section142 of Electricity Act, 2003 for notproviding desired RGMO/FGMO responsewithout any valid reasons.”

N.B. All ISGSs have been communicated about Hon’ble Commission’s order vide letter no ERLDC/SS/FGMO/2017/2505 dated 25-08-17.

Section 24• “….. The Committee (on implementation of FGMO /

primary response) has also recommended thatthere is no requirement for granting anyexemption even to LMZ units from operationunder RGMO/FGMO with manual intervention

• … has the option of either expediting the R&M ofold units which shall include installation of newEHG governors capable of providing adequateprimary response or

• to go in for retrofit of mechanical governors foradopting RGMO features or

• to operate on FGMO with manual intervention…”

• Primary response of ER ISGS units in terms of Regulation 5.2 (f), (g), (h) and (i) of the Grid Code, calculated based on ERLDC SCADA data will be uploaded to a web group called https://in.groups.yahoo.com/neo/groups/ er_gov_respons/info

– Members are requested to validate the response recorded at ERLDC with DCS data and to provide reason for not providing desired FGMO/RGMO response (if any)

– Request for joining the group can be sent to [email protected].

Reactive power performances of various units in the month of June,

2017

Annexure-B38

Voltage & reactive power injection (Unit MVArinjection-MVAr absorption in GT) at terminal point of generating units are compared for various generating units in ER.

– Scatter plot is plotted with taking

• Terminal voltage across x axis

• Reactive power injection across y axis

• (Nominal terminal voltage (kV), 0 MVAr) as origin

• MVAr injection should reduce with increase in terminal voltage

Response of the units whose MVArinjection increases with increase in

voltage

The units whose MVAr injection increases with increase in voltage

• Mejia B #7 & #8

*Based on available SCADA data at ERLDC

Response of the units whose MVAr injection decreases with increase in voltage but does not absorb reactive

power even in high voltage period
